Drop down List items getting Cleared after Post back in aspx page.

Open original thread

In my aspx page the DropdownList Items are getting binded when the page is not post back(first time loading) but when I clicked any button like (save ,edit)( all the drop down List items are getting Cleared.

can any one plz help, am i missing any settings for the dropdown list.

I put
Page.EnableViewState = true;
above the If(!ispostback)

The code inside the If(!IsPostback)
Parameters param = new Parameters();
DataSet datasetddlInternetwght = new DataSet();
datasetddlInternetwght = param.GetDDLListInternetWght();
ddlIntrntweight.DataTextField = datasetddlInternetwght.Tables[0].Columns["paramname"].ToString();
ddlIntrntweight.DataValueField = datasetddlInternetwght.Tables[0].Columns["paramvalue"].ToString();
ddlIntrntweight.DataSource = datasetddlInternetwght;

where Parameters is a class in a separate .cs file. I am getting the Data binded when the Page is loaded for the first time but when any button got clicked the items in the Drop down list(ddlIntrntweight) are getting cleared. i enabled the View state for the Drop down list;
